Avi, the Pentatonix bass vocalist, plans to appear in the last batch of shows for the act. Info for the performances is available at ptxofficial.com/tour.

During his heartfelt goodbye, Avi explains, "It's been extremely hard for me to not be able to see my family or friends when I need to or when they need to see me. It's been hard for me to just escape to nature when I'm feeling overwhelmed or when I just need time for myself."

He thanks Pentatonix fans in the message, saying it comes directly from his heart. Aca-scuse us while we wipe away our tears.
